HI there,

First of all, let me thank you for your work, both for discovering all this and for putting it all together in this guide.

I also have a Dell XPS 15z laptop with 1920 x 1080 native resolution (which I currently cannot use), so when I stumbled here, I thought it was the solution I needed. I am trying to get this to work with kernel version 3.8.2 but I cant get past the first step. I can add the extra info to grub
i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.i915_enable_fbc=1 pcie_aspm=force
But if i take out
the boot freezes with the message:
[Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS
I should mention that I could only see this message adding
no splash
to the grub command line. Otherwise, the screen just goes dark and "frozen".

Most posts I see about this "freezing during boot" problem consider the problem "solved" by adding nomodeset to grub. I don't call that a solution at all since it leaves me stuck with VESA.

Any thoughts?

Thaks in advance,
